kumpel [21]

Answer:

The inequality which represents the model for this situation is x-6\geq 17.

Step-by-step explanation:

Let Mr. Garcia has x number of desks initially.

He has been asked to give 6 desks to Mrs. Johnson.

Also, he needs to keep at least 17 desks for his students.

So, after giving 6 desks to Mrs. Johnson from the total number of desks he has, he must have at least 17 desks for his students.

Therefore, the inequality is: x-6\geq 17.

Hence, the inequality which represents the model for this situation is x-6\geq 17.
